[IDEA] Slave Crown Lux
Playing FF6 (modded) gave me an idea: What if there was some lore event (laughable, I know) in the future where Lux is captured by the Noxians and forced to wear a Slave Crown ala Terra? Basically, Lux would be mind-controlled by Swain and Leblanc, albeit temporarily (another subsequent lore event would see her being freed from mind control).
Dress her up in Noxian attire, change her dialogue to sound like a controlled drone, and you could have a neat skin. Good opportunity to give her unique dialogue toward Garen, Ezreal, Janna, Riven, etc.
